Having equipped ourselves with the very latest multi-purpose boring, surfacing and line boring CNC machinery we are not only able to undertake all aspects of cylinder block work but we are able to repeatedly achieve levels of accuracy exceeding original specifications.

Having the ability to re-machine cylinder blocks accurately is an essential part of the engine re-building process.  

Being able to repeatedly achieve exactly the same close tolerances ensures our cylinder blocks are machined to the very highest levels of accuracy.

We have developed specialist tooling which enables us to CNC machine the main bearing tunnels of all the Aston Martin cylinder blocks, an ability which we believe is unique to Aston Workshop.

Our Rottler F65 multi-purpose machining centre enables us to undertake the following  cylinder block machining on just one machine, thus increasing accuracy and reducing “set up” time.

  • Milling
  • Decking
  • Skimming
  • Line boring
  • Cylinder boring
  • Counter boring
  • Drilling
  • Tapping

Failure to undertake these disciplines to the highest levels of accuracy and quality will greatly affect the reliability,  longevity and performance of your engine.

Please contact us to discuss any block machining or repairs you may require.





"High Torque" 4.2 Litre DB4 Engine

The brief was simple. Produce a DB4 engine with a large increase in both power and torque, but retain the original look of the twin S.U carburettors.
